Piecewise linear contrast stretch is performed on an 8-bit image. The output (\( BV_{{out}} \)) would be zero for input value \( BV_{{in}} \leq 80 \). The output (\( BV_{{out}} \)) would be 255 for \( BV_{{in}}>120 \). For the remaining input values, \( BV_{{out}} = (2 \times BV_{{in}}) - 20 \). If \( BV_{{in}} = 120 \), then \( BV_{{out}} \) is __________ (Answer in integer).
